Add user defined extra capabilities
Provide a mechanism that will allow sys admins who are managing cinder
installations with multiple backends to assign key/value pairs to
backends. The key/value pairs can be used by the capabilities scheduler
to select between backends when requests specify volume types.
For example a sysadmin could specify the key 'service_level' with the
values 'high', 'medium' and 'low' for different backends. The sys admin
specifies the 'service_level' for each backend in cinder.conf as a json
string, for example:

Don't clear host_state_map when scheduling
host_state_map was added to scheduler for the purpose of caching latest
host_state in memory for scheduler. With this cache, scheduler has the
latest host_state (e.g. free_capacity, allocated_capacity, etc) of hosts
even hosts haven't reported their updated status to scheduler.
Unfortunately, this cache is flushed when scheduling pulling all available
volume services from DB in current implementation, which is a bug.
This change remove the host_state_map.clear() so that scheduler is able to
maintain an up-to-date (well, mostly) view of all volume services in memory.
Also, added code to remove non-active host from the cache every time when
scheduler handles a new request. Multi-line docstrings in cinder/scheduler/
host_manager.py are also fixed.

GlusterFS: Increase snapshot delete job timeout to two hours
Increase the timeout for Nova snapshot delete operations from ten
minutes to two hours. This helps prevent Cinder from terminating
operations prematurely that are still being processed by Nova.
It is not uncommon for snapshot delete jobs to run for longer than
ten minutes depending on the size of the snapshot and speed of the
storage backend.
This will be followed up with a more robust mechanism to keep track
of snapshot job progress as a later effort.
This patch changes the way the config options are
layed out in the cinder.conf to follow the
standards for grouping settings together.
Instead of using dynamic config names to group
settings together by fabric name, we look for
fabric groups based upon the fc_fabric_names.
We also create a new fc-zone-manager group
for all of the global fczm settings.

TSM backup driver changes to support file backup
Extend TSM backup driver to support backup of file based volumes,
as well as restore and delete of the backups. This in addition
to the current block based volume support. This involves determining
the type of volume this is requested to be backed up, and modifying
the dsmc command options accordingly. When a volume is backed
up, the backup mode and backup path are saved in the backup
service_metadata for use on restore and delete operations.
This commit includes some further refactoring based on pylint
feedback and system testing.
